Calculation Principles & Health Significance

Waist-to-Height Ratio (WHtR) is a unitless ratio calculated by dividing waist circumference by height. Studies suggest that WHtR is a better predictor of central obesity and associated risks (cardiovascular disease, diabetes, hypertension) than BMI.

Formula: WHtR = Waist Circumference / Height (must use same units)

General Rule: Keep your waist circumference to less than half your height (WHtR < 0.5).

WHtR Health Reference Ranges

Category Male Range Female Range Health Risk
Slim / Underweight < 0.43 < 0.42 Low
Healthy 0.43 - 0.52 0.42 - 0.48 Low
Overweight 0.53 - 0.62 0.49 - 0.57 Increased
Obese ≥ 0.63 ≥ 0.58 High
